Graph Theory for Dimensionality Reduction: A Case Study to Prognosticate Parkinson's

IEEE Annual Information Technology, Electronics and Mobile Communication Conference, 2020
In the present world, the commotion centering Big Data is somewhat obscuring the craft of mining information from smaller samples. Populations with limited examples but huge dimensionality are a common phenomenon, otherwise known as the curse of ...

Graph theory applications to continuity and ranking in geologic models

Computers & Geosciences, 1999
Abstract Continuity of permeable and impermeable units strongly affects the flow simulation response in geologic media. Important factors include the size of permeable and impermeable bodies, their internal geometries, and whether they connect to injection and production wells at different stages of reservoir development.

Application of the graph theory and matrix methods to contractor ranking

International Journal of Project Management, 2009
Abstract The most important element in construction procurement is the contractor selection, which can result from contractor’s ranking. Contractor prequalification is essential in most construction projects, and the process has been performed by many different methods in practice.

Reducing unnecessary handovers and improving ranking abnormality based on multi‐attribute decision making graph theory and matrix approach with Euclidean distance in heterogeneous wireless networks

Concurrency and Computation: Practice and Experience, 2023
SummaryNew mobile devices offer multiple network interfaces to allow the users to connect to the best available network. The heterogeneous networks can provide better internet connectivity to the users by means of vertical handover. The handover must be triggered at a suitable point of time to avoid mobility issues such as unnecessary handovers and ...

Graph theory application and web page ranking for website link structure improvement

Behaviour & Information Technology, 2009
Since the web is always developing, and users' needs are constantly changing, organisations in recent decades have increasingly focused on developing information and communication technologies (ICTs). To introduce new e-services to their customers, they have largely invested in web development and promotional activities.

Fast DCT+: A Family of Fast Transforms Based on Rank-One Updates of the Path Graph

arXiv.org
This paper develops fast graph Fourier transform (GFT) algorithms with O(n log n) runtime complexity for rank-one updates of the path graph. We first show that several commonly-used audio and video coding transforms belong to this class of GFTs, which we

Column and row subset selection using nuclear scores: algorithms and theory for Nyström approximation, CUR decomposition, and graph Laplacian reduction

arXiv.org
Column selection is an essential tool for structure-preserving low-rank approximation, with wide-ranging applications across many fields, such as data science, machine learning, and theoretical chemistry.

On the evaluation of ultra-high-precision frequency ratio measurements: examining closed loops in a graph theory framework

, 2016
A simple method is proposed for the evaluation of comparative measurements when closed measurement loops are present in the data. Using a graph theory representation of the data a basis for the residual subspace is readily identified that together with ...

A novel graph-based multiple kernel learning framework for hyperspectral image classification

International Journal of Remote Sensing
Multiple kernel learning (MKL) is an efficient way to improve hyperspectral image classification with few training samples by integrating spectral and spatial features.
